The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to the specific embodiment, structure, feature that foundation the utility model provides:
As Fig. 1～shown in Figure 3, a kind of New LED energy-saving tubular lamp comprises monochrome or seven colour tube lamps, and wherein each LED is for being connected in series, and the circuit when promptly several LED are connected in series is connected as LED1, LED2, LED3 to LEDn; It is characterized in that circuit adopts constant-current source E power supply, and each LED coupled in series two ends Zener diode Dw in parallel, as corresponding LED1, LED2, LED3 to LEDn respectively parallel connection be provided with Zener diode Dw1, Dw2, Dw3 to Dwn.Because circuit uses constant-current source E power supply, flow through the current constant of each LED, so LED is not fragile, even accidental damage also can be protected.Damage such as certain LED short circuit, because the constant current power supply, the electric current on other LED can not change, still can operate as normal; The damage if open circuit, owing to be provided with holding circuit, each LED parallel voltage-stabilizing diode Dw, electric current can flow through from Zener diode Dw, the same operate as normal of whole LED spot.Guaranteed under any circumstance not influence the spot overall work, the reliability height.
Constant-current source circuit is simple and practical, as shown in Figure 2, the directly alternating current 220V input of this constant-current source, through silicon bridge GQ rectification output direct current, inserting model is the special integrated chip IC of 22002P; R1 is for regulating the resistance of output current among the figure, and R2 is for regulating the resistance of sensitivity, and C1 is a smoothing capacity, and this constant-current source is constant current output under input 220V ± 10% situation.
The printed circuit board structural design as shown in Figure 3, long 1 meter of for example whole printed circuit board, constant-current source E circuit is located at an end of printed circuit board, only is provided with the pad A that LED lamp and corresponding each LED are respectively equipped with at main body to the other end of printed circuit board.From printed circuit board as can be seen, if intercept arbitrarily from printed circuit board other end LED pipe, intercepting place all has the corresponding in advance pad A that is provided with, and just can make it operate as normal as long as connect a short-circuit line in intercepting place.Like this, when needing the LED spot of different length, can carry out the LED cascade or the intercepting of any number as required within the specific limits, for example select each 100 of red, whites, green LED pipe etc., the security performance of circuit remains unchanged; Applying flexible is convenient, and is very practical.
